Personally the shallot feel great any way you hold it, tip up/down, blade in/out. I don't think there is anything bad about the shallot. Its a little slippery, but the grip ergonomics are so good it doesn't cause me any grief.
I too have gone from loving A/O to leaning more toward a manual flipper, it should last longer with less maintenance. The skyline is basically meant to be used holding it the regular way, index finger in choil and thumb on top spine, it fits funny otherwise.
I do really like the leek too, but its a little to small for me. Could get an S30V G-10 version though.
Overall I think the shallot is the best choice for you as long as you are not worried about someone gasping at such a long knife. Its EDC-able, tactical and has a refined aesthetic appeal.
